HOSE-Pl PE NOZZLE.

SPECIFICATION forming part of Letters Patent No. 245,559, dated August9, 1881. Application filed April 12, 1881. (Model) To an whom it mayconcern:

Be it known that I, JOHN E. PRUNTY, of Waverly, in the county ofBaltimore and State of Maryland, have invented certain Improvements inHose-Pipe Nozzles, of which the following is a specification.

This invention relates to the novel construction of ahose-pipe nozzle,whereby, at the pleasure of the fireman handling the same, a stream ofwater may be made to pass laterally and radially from the nozzle, andform a disk or sheet of water to protect the fireman from severe heatand smoke in the extinguishment of fires. The water ejected from thenozzle in the form of a sheet or disk, as described, may, however, beincreased in volume and employed in extinguishing fires in the holds ofvessels and other similar places. In this latter use of my invention thehose-nozzle is passed through the hatch or through a hole cut in thedeck of the "essel and held in an inverted position, so that the waterejected laterally from the pipe is thrown against the under side of thedeck and distributed over a large portion of theinterior of the hold.The lateral stream can also be employed in extinguishing fires inwarehouses and buildings generally, where communication with the firecan only be had safely through a hole cut in the floor of the room abovethe fire, or through awindow or skylight, and in many other cases whereentrance to the burning building is impossible or dangerous on accountofthe dense character of the smoke and the close packing of the materialson fire.

The said invention consists in providing a hose-pipe nozzle having ashut-offcock or valve therein with a series of lateral apertures and anexterior screw-sleeve adapted to be turned and thereby movedlongitudinally of the hosepipe nozzle to regulate the thickness of thesheet or disk of water projected from the nozzle, or to entirely closethe opening and prevent the lateral escape of water, as may be desired.

It further consists in a peculiar construction of the nozzle and theadjusting-sleeve, whereby the water ejected laterally from the nozzle isin the form of a sheet or disk instead of a series of independentstreams, as will hereinafter fully appear.

In the further description of my said invention which follows referenceis made to the accompanying drawings, forming a part hereof, and inwhich- Figure I is an exterior view of theimproved hose-pipe nozzle withthe lateral apertures partly open. Fig. 11 is a longitudinal section ofthe invention with the lateral apertures closed. Fig. III is across-section of the nozzle taken on the dotted line a 41.

Similar letters of reference indicate similar parts in all the views.

In the said drawings, A is the hose-pipe nozzle, having the usualshut-off cook or valve B. The lateral apertures in the hose-pipe nozzleare represented by a, and it will be seen that they are flared outwardlyto give to the disk of water ejected through them when fully opened oruncovered two concave faces, as indicated by the dotted lines to w and wa.

O is a screw-sleeve placed exteriorly of the nozzle and adapted to bemoved by hand longitudinally thereof to open and close the apertures a.

It will be seen by reference to the drawings that the lateral aperturesa do not extend, as such, to the circumference of the nozzle, but merelyconnect the interior of the pipe with an annular groove or space formedby the outer face of the sleeve 0 and the inner face of a projection onthe nozzle A. By this means the separate streams of water leaving theinterior of the pipe are united to form a continuous sheet before beingdischarged.

Supposing the cock B to be open and the aperture to uncovered or openedto a limited extent, a thin sheet or disk of water is interposed betweenthe fireman holding the hosepipe and the fire, which effectuallyprotects him from excessive heat and dense smoke,

while it does not obstruct his view of objects in front of him orinterfere with the effectiveness of the main stream of water deliveredfrom the nozzle.

To use the lateral stream of water for the purpose of extinguishing fireunder circumstances and in the manner before described, thsh ut-off cockis closed and the lateral apertures a opened to their full extent. Theentire discharge of water is now through the lateral apertures a, and ittakes the form indicated by the dotted lines 10 w and a: .00 beforereferred to.

I claim as my invention 1. Ahose-pipenozzle having a shut-off valve orcock therein, a lateral discharge-aperture situated in the rear of saidvalve or cook, and means for controlling or suspending the lateraldischarge independently of the said valve or cook, substantially as andfor the purpose specified.

2. A hose-pipe nozzle having an exterior circumferential grooveorlateral discharge-opening adjustable in width, in communication withthe interior of the nozzle by means of a series of aperturessubstantially as and for the purpose specified.

aperture, substantially as and for the purpose 2 5 specified.
